General Description
The MAX1340/MAX1342/MAX1346/MAX1348 integrate a
multichannel, 12-bit, analog-to-digital converter (ADC)
and a quad, 12-bit, digital-to-analog converter (DAC) in a
single IC. The devices also include a temperature sensor
and configurable general-purpose I/O ports (GPIOs) with
a 25MHz SPI-/QSPI-/MICROWIRE-compatible seri-
al interface. The ADC is available in a 4 or an 8 input-
channel version. The four DAC outputs settle within 2.0s,
and the ADC has a 225ksps conversion rate.
All devices include an internal reference (4.096V) provid-
ing a well-regulated, low-noise reference for both the
ADC and DAC. Programmable reference modes for the
ADC and DAC allow the use of an internal reference, an
external reference, or a combination of both. Features
such as an internal ±1°C accurate temperature sensor,
FIFO, scan modes, programmable internal or external
clock modes, data averaging, and AutoShutdown allow
users to minimize both power consumption and proces-
sor requirements. The low glitch energy (4nVs) and low
digital feedthrough (0.5nVs) of the integrated quad
DACs make these devices ideal for digital control of fast-
response closed-loop systems.
The devices are guaranteed to operate with a supply
voltage from +4.75V to +5.25V The devices consume
2.5mA at 225ksps throughput, only 22A at 1ksps
throughput, and under 0.2A in the shutdown mode. The
MAX1342/MAX1348 offer four GPIOs that can be config-
ured as inputs or outputs.
The MAX1340/MAX1342/MAX1346/MAX1348 are avail-
able in 36-pin thin QFN packages. All devices are speci-
fied over the -40°C to +85°C temperature range.
